Python 3 compatibility about toml

[uiri]

Yes, it is fully Python 2 & Python 3 compatible right now and shall remain that way for the foreseeable future. Continuous integration currently runs on Python 2.6, 2.7, 3.3, 3.4, 3.5, and 3.6.

I've added relevant classifiers to PyPI and a badge to the README although I'm not sure how long it will take the badge to update the info from PyPI.

I use python 2.6 or 2.7 usually. I believe that 2to3 fixes the two incompatibilities: xrange → range and unicode strings becoming default. Do you have any idea if it is possible to package two different versions for PyPI (one for python2 and one for python3) ?

[untitaker]

I don't recommend doing that. If 2to3 happens to fail at some part of your codebase, you'll have to write fixers for it, which become hard to maintain and so on. You can use u"" for unicode strings and b"" for bytestrings in Python 2.6+ and Python 3.3+. xrange can be either replaced by just range, which happens to exist in both versions (yeah, it returns different types, but both are iterable), or by using something like:

try:
    _range = xrange
except NameError:
    _range = range

Also, if you want some kind of trustworthy source, there's at least a PyCon talk by one of the core Django developers: http://pyvideo.org/video/1787/porting-django-apps-to-python-3

The only differences between a python 2 version and a python 3 version at the moment are: xrange vs range, unicode() vs str() and unichr() vs chr(). These really are minor differences. Given the current size of the codebase, I see no problem with maintaining two versions which are almost-identical --- one for python 2 and one for python 3. Even though I would have to manually 3to2 any patches for the python 3 version.

I'm just not clear on how to package one version for python 2 and one version for python 3.

You may use six to release only one package: http://pythonhosted.org/six/

@uiri I don't want to open a new issue just for asking that....

Is toml fully Python 3 compatible right now? If yes, could you please add a note to the readme or some other place, which is easy to find?

Thanks!
